HAIR CLIPPER.

Application filed December 17, 1928, Serial K0. 153,111, and in GermanyKay 4, 1828.

This invention relates to a hair clipper comprising-an adjustable combfor varying the cutting height during the cutting. The

hair clipper improved according to the invention presents the advantageover vhair clippers of known type that the adjusting comb is shiftablyguided in two directions the 'one at an acute angle to the other so thatthe comb ma be adjusted during the 1 hair clipping within the widestlimits in any desired distance from the plane in which the clippinknives are situated, or to move the same a ong the knives away from thecutting edges of the same of such a distance that it becomes ineffectiveand the hair clipper can be used for making, during the hair clipping,cuts from the minimum length to the maximum length. Inthis manner cutsof any des'red length can be made by means 30 of this hair clipperwithout the necessity of exchangin elements or of carrying outcomplicated adjusting work.

According to the invention the adjusting comb is movably held'by a slidewhich itself is guided on the machine frame near the cutting knives bymeans of a pull spring and connected at the other end to a hand lever insuch a manner that the adjusting can be efi'ected by accordinoscillation of the hand lever. At the first p ase of movement of thehand lever the comb which stands at a greater distance from the knifeplane is moved towards the knives to be then shifted along thestationary knife so that it moves back completely and becomesinefl'ective.

The guidin of the hair clipper and the adjusting of t e comb can becarried out with one hand accurately as is the case with hair clipperswithout 'an ad'usting comb. 40 n embodiment of t e invention is shown,lay way of example, in the accompanying rawings in whic Fig. 1 shows inside elevation, partly in longitudinal section, the improved airclipper, the comb being adjusted to a great distance from the cuttingpoint.

Fig. 2 is a view similar to Fig. 1, the comb being in a position closeto the cutting The hair clipper, consisting of .1. handle a a stationaryknife 6 and a movable knife 6, has a comb g in front of the stationaryknife I) which comb is held by a slide it and preferably constructed asa double comb in such a mannerthat a second comb g. is hingedlyconnected to thepoints of the stationary comb g which is rigidly fixedon the slide. A blade spring f serves to press towards the stationaryknife 6 the lower end of the comb g, which is oscillatably mounted onthe axle z. By the second combg' the hair are well guided, this being ofgreat importance for the proper execution of the cutting work. The slidek is pressed by the action of springs is, arranged near the cut tingknives, from below against the handle a. The rear end of the slide h ishingedly connected to a pull rod m which passes through the reartransverse wall a of the handle or casing a and which is at its other 7end pivotably connected to a hand lever pwhich is oscillatably mountedon an axle n. By means of this hand lever p and of the pull rod m thedistance of the comb g from the cutting knives b, d may be altered atwill during the clipping, it being merely necessary for this purpose tomake the lever p oscillate towards the casing a in opposition to thepressure of a spring a or to release the hand lever p sufliciently sothat the spring 8 can make it oscillate in opposite direction.

In order to adjust the machine for predetermined cutting lengths thepull rod m has several holes 0 and the transverse wall a has a bore 1-,so that, by means of a pin to be inserted through one of the holes 0into the bore r, the pull rod m and the hand lever p and through thesamefthe comb 9 can be secured in any position.

In order to determine the minimum length of the cut, a second row ofholes t, rpendicular to the direction of the row of oles 0, may be'arranged in the ull rod m. A pin inserted into one of sai holes t servesas abutment to limit, by striking against the inner surface of thetransverse wall a, the longitudinal displacement of the slide h, wherebyexciting of the desired minimum distance of the comb g from the knivesd, e is determined.

In the form of construction shown it is supposed, that the slide it besituated outable knife standing atan acute angle to said handle, a combin front of said knives, a hand lever oscillatably mounted on said 10slide shiftably mounted on the lower surhandle close to said knives andpivotably face of said handle its frontportion being connectedapproximately at the middle, to bent at the same acute angle at whichsaid said pull rod, and a blade spring acting upon 6 knives stand tosaid handle, a link connectthe inner end of said hand lever and pressingsaid comb to said slide, a spiral spring ing the same away from saidhandle. for pulling. said slide from below towards In testimony whereofI aflix my signasaid handle, a pull rod hingedly and adjust-ature. blymounted on the rear end of said slide, a WILLY BORE-MANN.
